Depressive mood, the single-parent home, and adolescent cigarette smoking.

The association between depressive mood and cigarette smoking among adolescents was examined within a multivariate model. Subjects were 205 eleventh graders (123 boys and 82 girls) enrolled in a Northeast metropolitan public high school for science-oriented students. Logistic regression analysis showed an independent relation of depressive mood, friends' smoking behavior, and living in a single-parent home with cigarette smoking. Depression scores correlated with the number of cigarettes smoked. These associations suggest that depressive mood and stress may contribute to the onset of smoking.
